I want to debug a C++ project in VSCode (on a Mac, using either GDB or LLDB). The program itself takes command line arguments like
./prog -input cf file_x.txt
This works fine when starting a debugging session in GDB on the command line.
In VSCode, I tried to adapt launch.json to read like this (only relevant lines shown):
"program": "${workspaceRoot}/build/prog",
"args": [
"-input cf",
"path_to/file_x.txt"
]
With this, I get @"Unknown option: \"-input cf\"\r\n" in the output and the process is not debugged; alternatively, I tried only one argument like so:
"program": "${workspaceRoot}/build/prog",
"args": [
"-input cf path_to/file_x.txt"
]
resulting in the same message. Have I missed something important?

To set command-line arguments in Visual Studio, right click on the project name, then go to Properties. In the Properties Pane, go to "Debugging", and in this pane is a line for "Command-line arguments." Add the values you would like to use on this line. They will be passed to the program via the argv array.
To do that, open C++ file in VSCode and either hit F5 or go to Debug -> Start Debugging and select C++ (GDB/LLDB) then select g++.exe build and debug active file .
Download & Install the C/C++ Extension We need to click on the extension button that displays a sidebar for downloading and installing the C/C++ extension in the visual studio code. In the sidebar, type C Extension. In this image, click on the Install button to install the C/C++ extension.
Run and Debug C/C++ Code You’ll notice that there is also a .vscodefolder in your sample project. To configure debug configuration, 2 files are required launch.jsonand tasks.jsoninside .vscodefolder. VSCode can create and auto-configure these files if we try to debug for the first time.
And how we can start debugging or launch a code file by passing command line arguments. For this, you would need launch.json. If you have, just edit it as I will discuss in this post. To create a new launch.json, click on Run -> Open Configuratio or Run -> Add Configuration
In addition to debugging a program, VS Code supports running the program. The Debug: Run (Start Without Debugging) action is triggered with Ctrl+F5 and uses the currently selected launch configuration. Many of the launch configuration attributes are supported in 'Run' mode.
